I know but these are existing properties. I'd like to re-use them as they have exported parser helpers - and I am unsure what kind of breakages changing them would cause. (The BD71837/BD71847 which introduced these properties are one of the PMICs which are pretty widely used.) Best Regards Matti Vaittinen

Actually, I think I can add support for rohm,dvs-run-microvolt and fellows to these same helpers so new devices can use appropriately named properties.
